Casio XJ-H1750 DLP Projector
What makes it interesting, however, and worth a close look, is that it coaxes that 4, lumens out of Casio’s hybrid light source, consisting of LEDs and a laser. It doesn’t hurt either that it offers excellent data image quality. The XJ-H has the distinction of being a third-generation model, with the implied improvements from lessons learned in earlier generations.
So although both projectors are most likely to wind up permanently installed or on a cart, the XJ-H is far less appropriate to carry elsewhere, even occasionally. Set up is standard fare, with a manual focus and manual 1. The back panel offers a reasonably full set of connectors, including an HDMI port for a computer or video source, two VGA ports for computers or component video, a xh-h1750 VGA port, and both S-video and composite video inputs.
The LAN port lets you both send data images and control the projector over a network. The interactive option is best ignored, however, given that with the projector’s standard throw, it would be hard to avoid shadows if you’re close enough to the screen to interact with it.
In its brightest mode it was easily bright enough for the inch wide inch diagonal image I tested with to stand up to the typical level of ambient light in a mid- to large-size conference room or classroom. In fact, it was too bright for comfortable viewing with the lights off.
One of the more unusual, and more eco-friendly, touches for the projector is its wide range of brightness level adjustments. Most projectors offer a bright mode and one eco mode that lowers brightness and power consumption.
In addition, they typically offer color mode presets that are primarily meant for adjusting color, but affect brightness as well. The XJ-H offers two non-eco modes plus five eco modes, with the least power-hungry mode using only about 35 percent as much electricity as the most power hungry according to my measurements, or 40 percent as much according to Casio’s ratings for peak power usage for each mode.
More precisely, I measured the range at to watts, depending on the mode. You can, in short, choose the least bright mode that offers the brightness you need, and use the color presets as they were intended, to pick the best color setting, rather than using them to adjust brightness as well. The XJ-H offers excellent data image quality, sailing through our standard suite of DisplayMate tests.
Colors were fully saturated, and color balance looked good, particularly in the eco modes, with suitably neutral grays across the entire range from black to white.
Text was crisp and highly readable down to the smallest sizes we test with.

Video image quality was also good for a data projector. Although the quality is limited by the XGA 1, by resolution, the projector did a good job maintaining shadow detail details in dark areas based on shading and it showed only a touch of posterization shading changing suddenly where it should change gradually on scenes where many data projectors do far worse.
Also very much worth mention is that the XJ-H shows fewer rainbow artifacts with light areas on screen breaking up into little red-green-blue rainbows than most DLP projectors.
These are caused by the way DLP chips create colors, and they are always a potential issue for single-chip DLP projectors. With the XJ-H, the artifacts show up so infrequently with data images that few, if any, people should find them annoying. With video, I saw them a little more often, though not as often as with many other DLP models.
Those who see the artifacts easily may find them bothersome for watching video, but most people shouldn’t have a problem with them. The projector’s audio system counts as another small plus, with a watt mono speaker that delivers reasonably high audio quality at reasonably high volume. Less convincingly in the plus column is xj-j1750 3D support, which is even more limited than the 3D in most data projectors, because it works only with input over the VGA port.
That means you can’t use it with xj-y1750 video converter to play 3D Blu-ray discs, and you can’t even use it with an HDMI-connected computer.
The XJ-H doesn’t qualify for the PCMag Greentech Approved seal, but it offers enough eco-friendly features to make them worth highlighting, starting with the five levels of power-saving eco modes and the solid-state light source. Also, in addition to being mercury-free, the light source offers a 20,hour lifetime. That means it should last the life of the projector and lower its carbon footprint, since no additional shipping is needed for replacement lamps.
Ultimately, the overall balance of brightness, high-quality data images, eco-friendly features, and low running cost make the Casio XJ-H Pro Series both an impressive projector and a potentially attractive choice for a mid- to large-size setting.
